T0 all whom t may concern Be it known that l, Josnrrr ANEInos Casini', a subject of the King of Spain, and resident of the borough of Brooklyn, in the county of Kings, city and State of New York, have invented certain new and useful improvements in "erforating Apparatus, of which the following is a specification.

This invention relates to punch presses and the like, and particularly to presses of this character fou operating upon flat stock or sheets, such as paper, for perforating sheets of paper for use in connection with loose leaf books, and it is the primary object of the invention to provide an improved punching or perforating machine for this purpose wherein the feeding of the sheets is progressive from the feeding end to the perforating means and advanced from the latter to deliver the same, the feeding of the sheets being alternately with the operation of the perforating means and the parts so timed with relation to each other that the material is progressively advanced to the perforating means, arrested in its advance for a time su'liiciently long for the perforat ing means to be actuated when the material. is delivered from the perforating means by advancing it to the point of discharge and concomitantly with the delivery of the material from the perforating means advance matcri al to the perforating means.

rlhe principal object of the invention is to provide improved means for progressively advancing the sheets to the perforating means, arresting the sheets in their advance and gauge the sheets in predetermined relation to the perforating means, and after the sheets have been operated upon by the perforating means advancing the sheets from the perforating means to deliver the same.

A further object of the invention relates to the provision of means in apparatus of this character for adjusting the punch and die. mechanism whereby the perforations may be variably positioned in the sheets.

@ther objects and advantages will hereinafter appear.

ln the drawings accompanying and forming a part of this specification Figure 1 is a plan view of a perforating machine, partly in section, illustrating an embodiment of my invention.

Figure 2 is a cross sectional view taken substantially on the line 2-2 of Figure 1 looking in ine direction of the arrows.

Serial No. 757,813.

Figure 3 is a longitudinal sectional view to show the progressive advance of the sheets to the perforating mechanism and the operative connection of the perforating or punching mechanism and feeding means to an operating shaft.

Figure 4 is a sectional detail view to show the means and manner of gauging the sheets relative tothe perforating mechanism; and

Figure `5 is an elevational view to show the adjustable mounting for the perforating punches.

Similar characters of reference designate like parts throughout the dierent views of the drawings.

In carrying out the embodiment of the invention illustrated in the drawings there is provided a framework including vertical end members or columns 6 having a suitable supporting base (not shown) and an intermediate transverse bed or table 7 arranged with a longitudinal slot 8 cut therethrough with individual dies in the form of perforated blocks 9 mounted on the bed to have adjustment longitudinally in said slot. A punch carrying head 1() is slidably mounted at its ends in guideways in the inner side of the columns, as at 11, to have reciprocatory movement toward and away from the table. The head carries punches 12 in alinement with the dies 9, said punches being carried by the head to have adjustment longitudinally thereof and relative to the dies. For this'purpose the head is arranged with a T-slot, as at 13, extending longitudinally thereof one wall 11i of which is releasably connected to the head as by bolts 15. The punches 12 are carried in blocks 16 arranged with a portion to correspond with the T slot 13 of the punch carrying head, and are secured in adjusted position by the releasably wall 11i of the head which is in the nature of a clamping member.

The punch carrying head is positively actuated to move it in a direction toward the die carrying table 7 by cams 17 on a driving shaft 18 journaled in the end members of the frame below the table, there preferably being two of these cams one adjacent each end of the shaft 18. The cams operate to actuate the punch carrying head through rollers 19 rotatably mounted in a bifurcated portion of carriers 2O therefor. The bifurcation of each carrier for the cam following' rollers straddle the cams with the legs of the bifurcation engaging at opposite ends of the cam and arranged with elongated openings 2l for the passage of the shaft 13 and permit of movement of the carriers transversely of the shaft. The carriers for the cam followers are adjustably connected to the punch carrying head by rods 22 having threaded connection 23 at one end with the carriers 2O and at the opposite ends with bosses integral with collars 24- loose on studs 25 fixed in and extending laterally of the heads adjacent the top thereof. The punch carrying head is urged in a direction away from thel table by springs 26 connected at one end to the carriers 2O and at the opposite ends to a hized member at the bottom of the bed or table, in the present instance shown as hooks 27 threaded into the table. The springs also serve to maintain the cam following rollers in operative relation to the cams.

To feed the work or material to the punch and die mechanism to be operated thereon, in the present instance comprising a plurality of sheets to be simultaneously perforated, although it will be obvious that a single sheet may be operated upon, the bed or table i' is provided with an extension 7 integral with the framework and which in effect is a continuation of the table 7. rThe sheets are successively or progressively fed to and arrested at the punch and die mechanism and after operation thereon by said punch and die mechanism delivered from the latter by further advancing the sheets. For this purpose `the table is arranged with sheet supports in the form of rails 23 fixed to the top of the table and its extension to extend longitudinally and above the same, said rails supporting the sheets adjacent the ends.

rllhe sheets are fed by fingers 29 engaging at the rear edge of the sheets, said fingers being pivotally carried, as at 30, in slots of bars 3l 'fixed to a carriage 32 by screws 33 so that said bars will be in. the same plane the bars 23 and support the sheets intermediate said latter bars. Vl'hel feed bars are also slidarbly supported in table 7. rlhe carriage with the feed finger carrying bars has reciprocatory movement imparted thereto through an eccentric 3d fined to the driving shaft 1S, the. eccentric being operatively connected to said feed carriage by a yoke 35 surrounding the eccentric having an adj ustable rod connection 36 with one arm of a( lever 3T pivotally supported at 33 in hangers 39 extending downward from the` table eX- tension 7, the opposite end of the lever 37 having a link connection Ll() with a. lug il extending downwardly from the carriage. The actuating cams 17 for the punch carrying head and the eccentric 341; are so const ucted and timed that when the head is in retracted position feeding movement will be imparted to the carrie for the feed finger carrying bars, and during the retracting movement of the carriage the'punch carrying head will be operated to perforate the sheets. rlhe feeding fingers are arranged in equidistant spaced relation on their carrying bars, they being urged by light springs 4:2 to position to project above the feed bars, and as said bars are moved forward the fingers will engage the. rear edge of the sheets and advance the same. By this arrangement during the retractive movement of the feed finger carrying bars an inclined rear or to-p edge of the fingers will engage the leading edge of the advanced sheets and be moved into the slots in the hars against the tension of the springs -12 and be engaged below the sheets during the retractive movement of the carrying bars for said lingers. As the lingers are moved out of engagement with the bottom sheet they will be moved upward in position to engage the rear edge of the sheets upon the successive movement of the. finger carrying bars. rlhe upward movement of the fingers is limited by a straight edge portion i3 of the fingers engaging with the end wall of the slots in which the fingers are mounted:

As stated, the present apparatus is particularly adapted for pcrforating sheets for use in loose leaf books, and it is essential that the sheets shall be perforated at a predetermined distance from the edge thereof. Means are therefore provided for positioning and gauging the sheets at the rear edge relative to the punch and die mechanism. This means comprises abutments in the form of lingers all pivotally carried at the rear end in a guide block 52 for the punches and the forward end engaging by gravit-y with the die carrying block 9, andi the forward end of the abutments arranged as a straight edge extending parallel to the axis of the punches. As the sheets are advanced to the punch and die mechanism the gauge abutments will be engaged by theV leading end of the sheets and during the advancing movement of the sheets will ride along the top of the sheets, and as the sheets are advanced beyond the abutment fingers, as shown in Figure 3, said fingers will drop behind the sheets. The feed fingers 29 are so arranged that at the terminus of the forward movement of the carrying bars therefor the fingers will be slightly in advance of said ahntment fingers. As the feeding lingers 29 are retracted the punches l2 are movedr toward the dies and during the initial movement of the punch carrying head cam edges 45 on loo projecting portions 46 of such head will en- Y gage a roller i7 carried at one end of levers 48 fixed to a rock shaft A-l-S) rotatably mounted in the standard G forwardly of the punch carrying head. This engagement of the cam heads with the rollers carried by the levers a8 will move said levers to cause fingers 50 carried by arms 5l carried by the shaft 47 to engage with the leading edge 0f the sheets and move the sheets rearwardly to abut and gauge the rear edge of the sheet relative to the gauges 44, as shown in Figure 4, and hold the sheets in such position during the punching thereof. During the punching of the sheets the finger carrying bars will be retracted and during this retracting movement of said bars the feed fingers 29 at the forward end of the feed bars will be positioned to engage in the rear of the sheets being punched. During the retracting movement of the punch carrying head the rock shaft 49 will bei moved to position the fingers 50 out of the path of movement of the sheets advanced from the punch and die mechanism by a spring 52 connected at one end and an arm 53 fixed on the rock shaft and the other end to a fixed part of a frame standard G. By the arrangement of the forward extending of the arms 5l and the mounting of the fingers 50 thereon to extend downward it is possible to adapt the mechanism to sheets of variable sizes for which purpose the arms are adapted to have adjustment in a longitudinal direction and secured in adjusted position by set screws, and the fingers 50 adjusted along the arms and secured in adjusted position by set screws, as shown.

To perforate the sheets at variable distances from the edge the gauge fingers 44 are adjustable. For this purpose said gauges are pivotally carried by blocks 53 slidably mounted in supports 54 to engage with adjustable abutments 55 threaded into the supports and arranged with a knurled finger piece to facilitate the adjustment thereof, the gauge carrying blocks 53 being drawn and held to the abutinents 55 by set screws 55 passing through said abutments 55 and having threaded connection with the gauge carrying blocks.

ln operation the sheets are placed on the supporting bars 28 and feed bars 31 with the rear edges abutting against pins 56 extending upward from the table extension 7 and between guides 57 for the side edges of the sheets, as shown at a in Figure. l. The guides are mounted on guide carriers 58 slidably mounted in the feed bar carriage 32 to have movement transversely thereof, said guides being urged in a direction toward the sheets by springs 59, with the feed bar carrier in its rearmost position these guides are maintained in spaced relation to the side edges of the sheets to compensate for variations in the piled sheets by rollers 60 mounted on studs projecting up from the guide carriers engaging with cam members 6l fixed to the feed bar carriage. During the initial forward movement: of said carriage the rollers 60 will ride od from the high portion of the cams 6l and the guides will be moved inward toward the sheets,

and should there be any sheets projecting or extending laterally of the pile they will be adjusted so that the side edges of all the sheets will be in parallel relation. As the feed bar carriage continues to move forward the sheets are positioned as shown atb in Figure l between side guides 62, and during the successive movement of the feed bar carriage the sheets are moved to the position c between side guides 63. During the retractive movement of the feed bar carriage the high portion of the cams G1 will engage the rollers 60 of the carriers for the side guides 57 and move said guides to the position shown in Figure l. The movement of the side guides 57 toward the sheets is controlled by abutments 64 adjustably mounted in the carriers for said guides.

lhile there is illustrated in the drawings an embodiment for carrying out the invention it will be obvious that various modifications may be made in arrangement and structure of parts without departing from the scope of the invention, and that portions of the invention may be used without others and come within the scope of the invention.
